GRINDING-MILL.

SPECIFICATION forming part of Letters Patent No. 294,673, dated March 4,1884.

Application filed November 28, 1883. (No model.)

To all whom it may concern B it known that I, EZRA RHoDEs, a citizen ofthe United States, residing at Cleveland, in the county of Ouyahoga andState of Ohio, have invented certain new and useful Improvements inGrinding-Mills; and I do-hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain improvements in mills for grinding corn,coffee, or other grains, in which the grade of grinding can be regulatedas desired; and it consists in certain novel constructions andcombinations of parts, all of which I will now proceed more particularlyto describe and claim, reference being had to the accompanying drawings,in which-- Figure 1 is a side elevation, partly in section. Fig. 2 is anend view Fig. 3, a perspective of the cylinder; Fig. 4, a'perspective ofthe concave.

Referring to said drawings,,A is the base of the mill, B the casing, Othe hopper, and D a discharge-spout leading from the casing.

E is a shaft journaled in the. sides of the casing.

F is a metal cylinder mounted on the shaft E, the periphery of saidcylinder being providedwith teeth a, as shown in Fig. 3. One end of thecasing is cut away, and in the opening thus made is hung the metalconcave G. b is a bolt on which the concave is hung. Said concave isprovided with teeth 0.

H is an arm secured to the outside of the concave, on the end of whichis hung aweight, H, which servesto hold the concave against the cylinderand permits it to be forced away when any hard substance comes betweenthe cylinder and concave.

I is a bearing on the back of the concave, in which is journaled theshaft I.

K are eccentrics mounted on the shaft I and bearing against the outsideof the casing, thus regulating the position of the concave with 5reference to the cylinder, said eccentrics being turned as it is desiredto move the concave toy position. The grain is then poured into thehopper, the cylinder revolved, and the grain fed between the cylinderand concave, where it is subjected to the grinding process and isdelivered by the dischargespout.

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- The hereindescribed grindingmill, comprising the casing B, cylinder F, concave G,arm H, weight H, shaft I, provided with the eccentrics K'and handle L,substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
